This is how you feel, but this is suboptimal. The drg aoe combo is good, paired with offgcds, Geirskogul and Nastrond. Just don't burn all your tp at once, ask for goad/tp regen to the other melee/ bard mch if you're dry, and if you reach 200-300 tp ish, go back to single target rotation. All of this is assuming the tank is doing big pulls.
